Question

9) Sendo U = {1, 2, 3, 4, 5, 6, 7, 8, 9}; A = {1, 3, 5, 7, 9}; B = {2, 4, 6, 8}

e C = {1, 2, 3, 5}, calcule:

A ∪ C
B ∪ C
A ∪ B
A ∩ C
A – C
C – A
A – B
B – A

Answer 1

Resposta:

A U C= ( 1, 2, 3, 5, 7, 9)

B U C= (1, 2, 3, 4, 5, 6, 8)

A U B= (1, 2, 3, 4, 5, 6, 7, 8, 9)

A ∩ C=( 1, 3, 5)

A – C= (7, 9)

C – A= (2)

A – B= (1, 3, 5, 7, 9)

B – A=(2, 4, 6, 8)
